Influence of weather on long-tailed bat detection in a North Island exotic forest

Accurate surveys and monitoring are required to guide the conservation and management of threatened species. Some fauna species that are cryptic or difficult to observe because they are nocturnal, mimic other species, conceal themselves, or can be incredibly hard to survey. Emergence and activity of these species may be related to complex environmental cues including weather and atmospheric conditions. The conservation status of New Zealand’s long-tailed bat (Chalinolobus tuberculatus) is Threatened-Nationally Critical.

A 20-Year Record of Alpine Grasshopper Abundance, with Interpretations for Climate Change

A 20-year capture-recapture study of alpine grasshoppers spanned three distinct sequences of abundance, featuring in turn dis-equilibrium, equilibrium and secondary cyclic equilibrium. This succession of population patterns in the most abundant species, Paprides nitidus, retained high stability between generations. It arose via superimposed life- cycle pathways and adaptive responses between grasshopper phenologies and their environmental constraints.
